3 Description
The DRV8881 is a bipolar stepper or brushed-DC
motor driver for industrial applications. The device
output stage consists of two N-channel power
MOSFET H-bridge drivers. The DRV8881 is capable
of driving up to 2.5-A peak current or 1.4-A rms
current per H-bridge (with proper PCB ground plane
for thermal dissipation and at 24 V and TA = 25°C).
Smart tune automatically tunes motors for optimal
current regulation performance and compensates for
motor variation and aging effects. Smart tune is
available on the DRV8881E. Additionally, slow, fast,
and mixed decay modes are available.
The PH/EN (DRV8881E) or PWM (DRV8881P) pins
provide a simple control interface. An internal sense
amplifier allows for adjustable current control. A lowpower
sleep mode is provided for very-low quiescent
current standby using a dedicated nSLEEP pin.
Internal protection functions are provided for
undervoltage, charge pump faults, overcurrent, shortcircuits,
and overtemperature. Fault conditions are
indicated by a nFAULT pin.
